According to Charles's Law, volume of an ideal gas is directly proportional to temperature at constant pressure,

V₁ / T₁ = V₂/T₂

where V₁ and V₂ are the initial and final volume respectively and T₁ and T₂ are initial and final temperature respectively.

Given, initial volume of balloon = 200 L

Initial temperature of balloon = 100 K

Final temperature of balloon = 400 K

Plugging the given data in Charles's law we can calculate the final or new volume of the balloon,

V₂ = V₁/T₁ x T₂

= (200 L / 100 K) x 400 K = 800 L
